Title: Streaming portions of data over a side channel
Inventor: WEI ZHANG
IPC: H04L9/32
Filed: 2019-05-24
Abstract: A payer/consumer controls/owns some digital asset associated with an output of a source blockchain transaction. A payee/vendor sends some data D0 to the payer. In response the payer creates an intermediary blockchain transaction TX1 for the charge associated with D0, which uses the source transaction output as its input, and sends it to the payee over a side/payment channel. The payee has a target transaction TXPwhich uses the output of the intermediary transaction as its input, and whose output is controlled by the payee. In response to the transmission of further data Dn etc, further intermediary transactions TXn for the increasing amounts of the cumulative charge are sent. Once the data transmission completes the payee records the latest/highest value intermediary transaction and the target transaction on the blockchain, thereby getting paid. That intermediary transaction spends the output of the source transaction and thereby invalidates the remaining intermediary transactions. The data may be chunks of streaming media or keys to unlock units of utility usage (gas, electric, water).
